Is tonight good for the stars?
One screen answers it - a Tonight verdict score, the golden and blue hours, the Milky Way core, dark-sky windows, and a sun and moon shot planner. Computed on your device. No account, no cloud, no subscription.
Astronomy, weather, and a planning engine fused into a single answer. The almanac and sky math run on your device; live conditions come from open weather and map services. No account, no ads, no subscription.
A single 0-100 score for exactly what you're planning - Milky Way, stargazing, the moon, a nightscape, or aurora. It weighs hours of true darkness, moon interference, cloud cover, and your sky's light pollution into one honest answer: is tonight actually good?
Sunrise, sunset, the golden and blue hours, and the full twilight ladder from civil to astronomical. Moon phase, illumination, and rise and set - all with a live sun-path arc.
Galactic-core rise, peak, and set with a Poor-to-Excellent quality grade, plus the moonless dark-sky window forecast so you know the exact hours worth shooting.
Which planets are up right now, where to look, how bright they are, and their current phase - all computed on-device for your exact time and place.
Find the exact days the sun or full moon lines up with your chosen direction. Azimuth-crossing and multi-day alignment search for that hero shot - all offline.
An interactive map that caches the tiles you have viewed, so it keeps working with no signal out in the field. Drop a pin and see its bearing, distance, and the exact date the sun or moon lines up behind it.
Solar and lunar eclipses computed on-device from the real ephemeris and filtered to your location, so the list only shows the ones you can actually step outside and see.
Current temperature, cloud cover, and a clear-sky clarity verdict for each saved location, pulled live from Open-Meteo - free, no API key. The detailed hour-by-hour forecast is a Pro upgrade.
A live Kp index from NOAA, your geomagnetic latitude, and a plain verdict for tonight - plus a 24-hour Kp strip so you can see the activity building before it peaks.
The next visible pass of the International Space Station over your location, computed on-device from live orbital data - rise time, direction, and peak elevation.
Widgets that refresh on their own in the background, so the sky stays current on your home screen even after the app has been closed for hours.
Three surfaces - Light, Dark, and true-black AMOLED - and any color you want, from a set of curated accents to your own exact custom shade. The whole interface recolors, not just one highlight. Full screen-reader support with spoken summaries for the sky charts, plus dynamic-type support throughout.
All 88 constellations and the bright stars, mapped over your sky in a live, free star chart - named and computed entirely on your device, no connection needed. The point-and-identify AR sky finder is a Pro upgrade.
The astronomy engine runs entirely on your device. No sign-up, no account, no ads, no location harvesting. Buy it once and own it - no subscription, ever.
Every screen is computed on your device - dark, AMOLED, or light, in any accent color you choose. Shown on Android; the same app runs on iPhone and iPad.
Almanox runs a full astronomy engine locally. No account, no sign-up, and it works with the signal off - the sky is the same whether or not you have bars.
Use your current location or save the places you shoot from. Almanox computes the sun, moon, and sky for exactly where you stand.
One score answers the only question that matters - is tonight worth it? See the best dark-sky window, the Milky Way core, and how much the moon gets in the way.
Find the exact days the sun or full moon lines up with your direction, catch the golden hour, and get an alert before the sky is ready.
The words the whole app is built around - and why each one is a reason to keep Almanox in your pocket.
Almanox was built to keep to itself. No account, no ads, no location harvesting - just the sky, computed on your device.
The astronomy engine runs entirely on your phone. Sun, moon, twilight, Milky Way, and the shot planner all work with no connection at all.
No sign-up, no email, no MiyaraHub login. Download it, open it, and you are planning - nothing to create, nothing to remember.
Location is used only to compute your sky and fetch local conditions - never sold and never used to profile you. Weather comes anonymously from Open-Meteo, with no account or key.
Buy it once and own it. No subscription, no recurring charge, no paywalled updates - the opposite of how most photo apps are priced.
No ad SDK, no ad networks, no data brokers. Almanox uses anonymous, first-party analytics to see which features get used, plus crash reporting when something breaks - never tied to your identity, never sold.
The same beautiful, offline planner across iPhone, iPad, and Android - wherever you shoot.
Everything you need to know about Almanox.
Everything you need to answer "is tonight worth it" is free. Pro ($12.99, one time - no subscription) adds the deep planning tools. Every locked feature shows a real sample first.
